Screen Reference
Seize When Maintenance Busy
This field only affects ports on TN760C (or later release), TN767, and TN464C (or later release)
circuit packs. It indicates whether this media server or switch generates an outgoing seizure
when a trunk in this trunk group is maintenance busied and whether the far-end server or switch
is administered to do likewise. This supports the Electronic Tandem Network Busyout feature,
which is intended to prevent a far-end server or switch from reporting problems with a trunk that
has been removed from service on your end. This field's setting does not affect the behavior of
the far-end server or switch; it controls the behavior of your media server or switch and defines
the expected far-end behavior.
For DIOD trunks using TN464F (or later release) or TN2464, displays only when the Group
Type field is diod and the Trunk Signaling Type field is pulsed, cont, or dis.
Valid entries
near-end
far-end
both-ends
If a media server or switch generates an outgoing seizure when a trunk is busied out, the
seizure will probably cause alarms at the far-end server or switch, perhaps leading to a far-end
maintenance busy out, unless the far-end server or switch is administered to expect this
behavior.
If the administered value of this field is either far-end or both-ends, any abnormally long
incoming seizure (including failure to drop from a completed call) is assumed to be the result of
a far-end maintenance busy condition. Note that this assumption might be incorrect, since the
abnormally long seizure might actually be due to failure of the trunk circuit. Regardless of the
cause of the abnormally long seizure, your server running Communication Manager does the
following things:
1. Generates a warning alarm indicating that the trunk is assumed to be maintenance busy at
the far-end
2. Removes the trunk from service
3. Keeps the trunk out of service until a far-end disconnect is received
Allowable values depend on the entry in the Direction field: check the online help in Avaya
Communication Manager.

Usage
Enter near-end if Communication Manager generates an outgoing seizure
when a trunk is maintenance busied, but the far-end server or switch does
not. The seizure is maintained until the maintenance busyout is released.
Enter far-end if the far-end server or switch generates an outgoing seizure
when a trunk is maintenance busied, but this server running
Communication Manager does not.
Enter both-ends if both this server running Communication Manager and
the far-end server or switch generate an outgoing seizure when a trunk is
maintenance busied.
